Black Magical Dice

Hi,

I 'm writting this instructable from France and my English is a little poor...so sorry for my

meager explanations.

After seeing a few of electronic dices on differents blogs, I wished to make one smaller than possible, while inserting the logical part.

Just for a personnal challenge. The result measured 18 mm ...

Use 7 white LEDs (1.5 mm) and CMS résistors, wired with

a thin copper wire. The platform is printting with PLA filament.

PLA for the translucide part,

ABS for the half-cube.

After inserting the platform, I flowed few of resin inside.

Welcome dear Attiny !

Arduino programmation on DIY shield.

I resumed a dice GitHub's program, and add a scrolling effect for the LEDs. More attractive.

All the electronics come in the top part.

ABS for the Half-cube,

PLA for battery plate.

For the power supply, I used a simple coin cell.

I managed to find THE smaller tilt switch in market (12*3 mm !) …

Before assembly, I also added a micro-switch between the two parts, for the general supply.

The two parts were glued directly to the extruder outlet.

All ABS parts have been polished in vats of acetone … and elbow grease ...

There you go !

… your best friend for the production, reading glasses !!!!
